Abstract
The present invention relates to a technique for controlling the creation of process instances within an execution environment such as a Workflow Management System. Upon receiving a request to create a process instance and corresponding input data to be processed by the process instance, a process instance identifier is first constructed for the process instance to be created based on the provided input. Next, the create request is executed, but only if no process instance exists or existed with the same process instance identifier. In the case where a process instance already exists or existed with the same process instance identifier, the present invention permits a user-defined action to be carried out to avoid an identifier conflict.
